WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 716,271, dated December 16, 1902.

, application filed April 12,1900. Renewed October 1, 1902. Serial No. 125,602. (No model.)

To all whom it may concern:-

i Be it known that I, CHARLES W. ONEILL, a citizen ofthe United States, residing at Peoria, in the county of Peoria and State of Illinois,have invented certain new and useful Im provements inWater-Heaters and Ido here by declare that thefollowing isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certainnew and usefulimprovements in water-heaters by means of which a very useful and eifective device is provided forthe purpose that is comparatively cheap at first cost.

More particularly, my invention relates to a Water-heater of the class commonly known as instantaneous heaters, which are adapted for use particularly for bath purposes, but may be applied as readily for other uses to great advantage. L I a The object of my invention is to provide constructive means and mechanism for receiving and so directing and carrying a sup ply of water that it will be readily and quickly heated duringits passage through the heater I mechanism and discharged from the same in a suitable manner to be used for bath and other purposes. I

My invention consists, essentially, in the provision of a suitable receptacle provided with a combustion-chamber, a series of circumferentially-arranged vertical tubes, substantially conical in form, extending from the combustion-chamber to a suitable point ator near the top of the receptacle, a cover or lid for the receptacle provided with a centrally disposed tubular extensiontherefrorn, a dia phragm carried within the receptacle at a point removed from thebottom edge of the receptacle which forms a dividing-partition between the combustion-chamber and main body of the receptacle an'd having a depending flange carriedadjacent to the wall of the receptacle,butsufficientlyremovedtherefrom to provide a compartment or pocket between the flange and the Wall, of a diaphragm located within the receptacle at a point just beneath the upper ends of the tubes and provided with openings to permit the-carrying of the tubes therethrough and sufficiently large to provide an opening of suitable diameter around the same, a disk or plate supported above the upper ends of the tubes and of suitable means for directing and supplying water to said heater as well as for heating the same, andin the provision of details hereinaftermore fully set forth, and illustrated in the accompanying drawings, in which-- Figure l is an elevation in section of myimproved heater. Fig. 2 is a cross-section at a suitable point at the upper end of the same and Fig. 3 is a cross-section of the same at a point about middle thereof.

In" the drawings like numerals indicate the several corresponding parts of the figures, in which- 1 indicates or refers generally to a suitable receptacle or tank expanded at a point near the bottom to increase the diameter thereof and forming the combustion-chamber 3.

2 is a suitable lid or cover for the body detachably secured thereto and is provided with the centrally-disposed tubular extension 2, as shown.

The receptacle or tank is provided with a suitable bottom 4, arranged at a point somewhat removed from the lowerbottom edge of the same and has the depending flange or circular extension thereof, 4, which is secured at a suitable point to the side wall of the receptacle 1. The flange is aranged to' form the inner wall and bottom of a compartment 13, which may be of suitable depth, arranged to be located between the flange and wall of the receptacle, as shown. I

9 represents suitable tubes arranged in the receptacle and open at their upper and lower ends and substantially conical in form and extend up from the bottom 4 to a suitable point just below the top ofthe receptacle or tank. At a suitable point removed from the upper end of the tubes and below the same is shown adiaphragm 4 which divides the receptacle into the compartments ltand 4! and is provided with the openings I at", through which the tubes 9 are carried and of a diameter larger than the tubes at this point, arranged so as to leave an opening between the wall of the tubes and the diaphragm for the passage of the water therethrough, as will be hereinafter fully set forth.

10 is a centrally-disposed water-pipe extending up through the tube 9 and terminating at a point above the same and is connected with the main water-supply 10 in the compartment 3 of the receptacle. This water-supply pipe is provided with a valve 11, by which the supply of water may be turned on or off.

5 designates a conical-shaped disk or plate supported above the tubes and by the diaphragm 4 by a series of plates or other suitable means to elevate the same above the diaphragm by any preferred means and is provided with a centrally-disposed perforation through which the pipe 10 protrudes. Supported above the conical-shaped disk and by a series of plates 6 is a suitable hood or sprayer 6, having a concavo-presented face above the feed-water pipe 10. The hood is shown of a smaller diameter than the disk, and the end of the water-pipe is adjacent to the concave face thereof, as shown.

In the compartment 3 I have shown in outline a suitable reservoir 7, with burners 8 at suitable points around the same coincident with the conical tubes 9 and equal in number, air-openings being provided in the burners and a supplypipe 1O communicating with the reservoir7 through suitable coupling and provided with a valve 12 for regulating the flow of gas orits equivalent to the reservoir.

3 is a suitable outlet-pipe for the heater located at asuitable point on the body of the same and may be provided with or without aspigot, as desired.

In the construction of the heater as above set forth I have aimed at several features which go to make a perfect water-heater for bath and as well for other purposes-such as for cooking, &c.which will instantaneously heat the water as the same is admitted to the heater proper and, further, to prevent the gases from entering the water, which does very little harm to water for bathing purposes, but almost wholly unfits itfor cooking purposes. I accomplish this by admitting the water to the heater in such a manner that itpasses around the mechanism for heating the same and admits the heataud conveys it through suitable means without coming into direct contact with the Water.

The operation of the same may be described as follows: \Vater being introduced to the heater through the pipe 10 and passing up through the feed-pipe 10, the discharge of the same will be against the concave surface of the sprayer 6, distributing itself evenly over the surface of the disk or plate 5 and thence to the diaphragm 4, where it will seek the openings 4 through which the pipes 9 protrude, and pass down around the same into the compartments 13 and 1, from which it will pass out through the outlet 3. Upon turning the gas into the reservoir 7 and light ing the burners 8, the products of combustion will pass upward through the respective tubes coincident with the burners, up and around the plate 5, into compartment 4? and escape through the tubular extension 2* after imparting the heat to the tubes 9, around which the water passes as it drops back into the heater proper and radiating sufficient to heat any water contained within the heater. The gas escaping out of the tops of the tubes 9 has so short a contact with the water passing from the pipe 10 to the body of the heater that it enters the same practically free from the odors of the gas, which is not the case when the gas and heat pass up through the Water and come into direct contact therewith.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a water-heater, the combination of an outer shell, a series of cone-shaped heat-tubes communicating with a combustion-chamber, a conical-shaped disk suitably supported above the upper ends of the tubes and surrounding the series, a water-conveying pipe passing upward in the shell and through the conical disk, a hood supported by the conical disk and above the water-pipe arranged to spray the water over the disk and means for causing the water descending into the shell to pass down and around the tubes, substantially as described.

2. In a water-heater, the combination of an outer shell, a combustion-chamber, a series of tapering heat-tubes leading from the combustion-chamber, a diaphragm arranged in the shell at a point near the upper end of the tubes, and having enlarged openings around the tubes, a conical-shaped disk raised above the ends of the tubes and surrounding the same, a concave hood or spreader supported by the conical disk and a water-conveying pipe terminating at a point above the conical disk through which the same extends, substantially as described.

3. In a water-heater, the combination with the outer shell 1, provided with a combustionchamber, the diaphragm 4, heat-tubes 9, extending from the combustion chamber through enlarged perforations or openings in the diaphragm, central tube 9, conicalshaped disk 5 raised above the ends of the tubes, pipe 10 extending upward in the tube 9, the upper end terminating adjacent to means for spraying water over the disk 5, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES W. ONEILL.
